Heh, I applied for and landed a position on the SRE team of a youngish startup that is almost entirely remote. I'm 55 and there is one other guy in his 40's I think who works out of Northern Cal. Other than him I'm 20 years older than everyone else and it's been a blast. We recently did a week-long retreat and I had a truly good time, which surprised me. Really the only thing I can say after 20 years in the business is you just never know. I got lucky this time around and fell in with a group of people who are perfect for me.
